"Riya":http://www.riya.com promises big, and seems to have the technology to back it up. Photo sharing service with face recognition seems like a good idea, if you take a lot of party pictures.

But I don't take many peoples' picture, and hardly put them online because people can and does get offended for it. So, the novelty faded pretty quick for me.

Without the facial recognition, the rest of the package is pretty weak. It does offer tagging, with special treatment given to location tagging. But the UI is slow, and it does a poor job at resampling large images. Flickr was much smoother in beta.
